From b05bfc603689419dc515a656b9fc711d79994f13 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 26 Nov 2019 16:29:34 -0500 Subject: core/memory: Migrate over Read{8, 16, 32, 64, Block} to the Memory class With all of the trivial parts of the memory interface moved over, we can get right into moving over the bits that are used. Note that this does require the use of GetInstance from the global system instance to be used within hle_ipc.cpp and the gdbstub. This is fine for the time being, as they both already rely on the global system instance in other functions. These will be removed in a change directed at both of these respectively. For now, it's sufficient, as it still accomplishes the goal of de-globalizing the memory code. --- src/core/hle/kernel/address_arbiter.cpp | 28 +++++++++++++++-------- src/core/hle/kernel/hle_ipc.cpp | 12 +++++----- src/core/hle/kernel/mutex.cpp | 2 +- src/core/hle/kernel/svc.cpp | 16 ++++++++----- src/core/hle/service/audio/audout_u.cpp | 6 +++-- src/core/hle/service/ldr/ldr.cpp | 5 ++-- src/core/hle/service/lm/lm.cpp | 10 ++++---- src/core/hle/service/nvdrv/devices/nvhost_gpu.cpp | 4 ++-- 8 files changed, 50 insertions(+), 33 deletions(-) (limited to 'src/core/hle') diff --git a/src/core/hle/kernel/address_arbiter.cpp b/src/core/hle/kernel/address_arbiter.cpp index 7f9a559d2..07f0dac67 100644 --- a/src/core/hle/kernel/address_arbiter.cpp +++ b/src/core/hle/kernel/address_arbiter.cpp @@ -67,12 +67,14 @@ ResultCode AddressArbiter::SignalToAddressOnly(VAddr address, s32 num_to_wake) { ResultCode AddressArbiter::IncrementAndSignalToAddressIfEqual(VAddr address, s32 value, s32 num_to_wake) { + auto& memory = system.Memory(); + // Ensure that we can write to the address. - if (!system.Memory().IsValidVirtualAddress(address)) { + if (!memory.IsValidVirtualAddress(address)) { return ERR_INVALID_ADDRESS_STATE; } - if (static_cast(Memory::Read32(address)) != value) { + if (static_cast(memory.Read32(address)) != value) { return ERR_INVALID_STATE; } @@ -82,8 +84,10 @@ ResultCode AddressArbiter::IncrementAndSignalToAddressIfEqual(VAddr address, s32 ResultCode AddressArbiter::ModifyByWaitingCountAndSignalToAddressIfEqual(VAddr address, s32 value, s32 num_to_wake) { + auto& memory = system.Memory(); + // Ensure that we can write to the address. - if (!system.Memory().IsValidVirtualAddress(address)) { + if (!memory.IsValidVirtualAddress(address)) { return ERR_INVALID_ADDRESS_STATE; } @@ -109,7 +113,7 @@ ResultCode AddressArbiter::ModifyByWaitingCountAndSignalToAddressIfEqual(VAddr a } } - if (static_cast(Memory::Read32(address)) != value) { + if (static_cast(memory.Read32(address)) != value) { return ERR_INVALID_STATE; } @@ -134,12 +138,14 @@ ResultCode AddressArbiter::WaitForAddress(VAddr address, ArbitrationType type, s ResultCode AddressArbiter::WaitForAddressIfLessThan(VAddr address, s32 value, s64 timeout, bool should_decrement) { + auto& memory = system.Memory(); + // Ensure that we can read the address. - if (!system.Memory().IsValidVirtualAddress(address)) { + if (!memory.IsValidVirtualAddress(address)) { return ERR_INVALID_ADDRESS_STATE; } - const s32 cur_value = static_cast(Memory::Read32(address)); + const s32 cur_value = static_cast(memory.Read32(address)); if (cur_value >= value) { return ERR_INVALID_STATE; } @@ -157,15 +163,19 @@ ResultCode AddressArbiter::WaitForAddressIfLessThan(VAddr address, s32 value, s6 } ResultCode AddressArbiter::WaitForAddressIfEqual(VAddr address, s32 value, s64 timeout) { + auto& memory = system.Memory(); + // Ensure that we can read the address. - if (!system.Memory().IsValidVirtualAddress(address)) { + if (!memory.IsValidVirtualAddress(address)) { return ERR_INVALID_ADDRESS_STATE; } + // Only wait for the address if equal. - if (static_cast(Memory::Read32(address)) != value) { + if (static_cast(memory.Read32(address)) != value) { return ERR_INVALID_STATE; } - // Short-circuit without rescheduling, if timeout is zero. + + // Short-circuit without rescheduling if timeout is zero. if (timeout == 0) { return RESULT_TIMEOUT; } diff --git a/src/core/hle/kernel/hle_ipc.cpp b/src/core/hle/kernel/hle_ipc.cpp index be24cef06..03745c449 100644 --- a/src/core/hle/kernel/hle_ipc.cpp +++ b/src/core/hle/kernel/hle_ipc.cpp @@ -214,10 +214,11 @@ ResultCode HLERequestContext::PopulateFromIncomingCommandBuffer(const HandleTabl ResultCode HLERequestContext::WriteToOutgoingCommandBuffer(Thread& thread) { auto& owner_process = *thread.GetOwnerProcess(); auto& handle_table = owner_process.GetHandleTable(); + auto& memory = Core::System::GetInstance().Memory(); std::array dst_cmdbuf; - Memory::ReadBlock(owner_process, thread.GetTLSAddress(), dst_cmdbuf.data(), - dst_cmdbuf.size() * sizeof(u32)); + memory.ReadBlock(owner_process, thread.GetTLSAddress(), dst_cmdbuf.data(), + dst_cmdbuf.size() * sizeof(u32)); // The header was already built in the internal command buffer.
